1 Claim. (Cl. 25--1) My invention relates to a brick sanding device.

An important object of the invention is to provide a brick sanding device in the nature of an attachment for brick making machines.

A further object of the invention is to provide a sanding attachment for brick making machines which will apply the sand to one side surface and to the opposite ends of the brick, as the bar of clay emerges from the extrusion die of the machine.

A further object is to provide a brick sanding device which will effect a saving of sand, and which applies the sand evenly to the three faces of the brick which it is desired to sand, and only to these three faces.

Another object is to provide brick sanding means of simplified and durable construction, which is reliable and eicient in operation, easy to service, and economical to manufacture.

A still further object of the invention is to provide a brick sanding device, including a sanding hopper which is readily removable from the remainder of the device, without requiring total disassembling of the same.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

Figure l is a fragmentary perspective view of a brick sanding device embodying the invention, and showing the same in use upon a brick making machine,

Figure 2 is a side elevation of the sanding device,

Figure 3 is an end elevation of the device, part broken away, v

Figure 4 is a vertical section taken substantially on line 4-4, Figure 2,

Figure 5 is a horizontal cross section taken on line 5 5 of Figure 2,

Figure 6 is a horizontal section taken on line 6-6 of Figure 2,

Figure 7 is a vertical section taken on line 7 7 of Figure 6,

Figure 8 is a side elevation of the sanding hopper on a reduced scale,

Figure 9 is a bottom plan view of the hopper, and

Figure l0 is a perspective view of a sanded brick after the same has been cut from the bar of clay.

In the drawings, where for the purpose of illustration is shown a preferred embodiment of the invention, the numeral designates generally the extrusion die of a brick making machine, having the usual tapered rectangular die opening 16 which imparts the proper rectangular cross sectional shape to the bar of clay to be made into bricks, as the bar emerges from the die 15. The die is provided adjacent its discharge end with a flat rectangular mounting flange or plate 17, preferably formed integral therewith.

My sanding device proper comprises a rectangular llat adapter plate 18, for engagement with the mounting flange 17, and rigidly secured thereto by means of bolts 19 or the like. A compressible gasket 20 of any desired material is preferably disposed between the flange 17 and adapter plate 18, as shown. The adapter plate 18 has a rectangular opening 21 registering with the discharge end of the tapered die opening 16, and the opening 21 is preferably the size and shape of the completed extruded or shaped clay bar 22, from which the individual bricks 23 are subsequently cut by means not shown CTI in the accompanying drawings, and forming no part of the present invention.

A first or rear rectangular tubular casing section 24 or guide is provided adjacent to the forward side of the adapter plate 18, and this casing section has both ends open and embodies a rectangular bore or passage 25 of the same size and shape as the rectangular opening 21, for the passage of the extruded clay bar 22. The casing section 24 is provided upon its top and bottom walls and adjacent its rear end with transverse enlargements or ribs 26, extending preferably for its entire width. Upper and lower pairs of screw threaded mounting bolts 27 have their rear ends secured within screw threaded openings 29, formed in the forward face of the adapter plate 18, above and below the casing section 24, and near the four corners of the latter. Clamping angle members 29, L-shaped in cross section have openings in their vertical flanges 30 which receive the mounting bolts 27, and the flanges 30 engage the forward sides of the flanges 26, and clamp the same tightly against the forward face of mounting plate 18. Adjustable lock nuts 31 are carried by the mounting bolts 27, forwardly of the angle members 29 for holding the same in clamping engagement with the flanges 26.

A second or forward rectangular tubular casing section 32 or guide, substantially identical with the casing section 24 is provided, and spaced somewhat forwardly of the casing section 24, as shown. The casing section 32 has a rectangular bore 33 similar to the bore 25, but preferably about 1/16 of an inch larger on a side than the bore 25. The rectangular bore 33 is somewhat en larged, to accommodate the sand to be applied to the bar of clay 22 by my device. I have illustrated the rectangular bores 25 and 33 as straight rectangular bores, for receiving the extruded rectangular clay bar 22 from the die 15, and it should be understood that the bores 25 and 33 may taper somewhat toward their discharge ends, if it is preferred to further extrude the clay bar, subsequent to its discharge from the die aperture 16. In any event, the bore 33 is preferably about 1/16 of an inch wider on each side than the bore 25 for the above stated reason.

The forward casing section 33 is provided upon its top and bottom walls with transverse enlargements or ribs 34, preferably extending for its entire width. The mounting bolts 27 extend over the gap or space between the casing sections 24 and 32, above and below the casing sections, as shown, and the forward ends of the bolts 27 may terminate near the longitudinal center of the forward casing section 32, as indicated. Forward clamping angle members 35, similar to the angle members 29 are provided, and the vertical flanges 36 of these angle members have openings receiving the bolts 27. Clamp plates 37 and 38 are arranged rearwardly of the angle members 35, in opposition thereto, and have openings receiving the mounting bolts 27. The ribs 34 are clamped between the clamp plates 37 and 38 and the corresponding vertical flanges 36 of angle members 35, and nuts 39 and 40 are provided upon the bolts 27, rearwardly and forwardly of the clamp plates and angle members, for holding the same in clamping engagement with the ribs 34. The casing sections 24 and 32 are thus rigidly supported with their rectangular bores 25 and 33 in alignment, for receiving the longitudinally moving clay bar 22.

I provide a sanding hopper 41, formed of heavy guage sheet metal, or the like. The hopper 41 has vertical end walls 42 and side walls 43, as shown, and the top and bottom ends of the hopper are entirely open. The upper portions 44 of the hopper side walls are inclined and diverge upwardly, so that the top of the hopper is flared between its end walls 42, for receiving a substantial quantity of sand, which is fed by gravity toward the bottom of the hopper. Below the upper flared portion of the hopper, the same is relatively narrow, Figures 2 and 7, and the lower portion of the hopper s only slightly wider than the space between the casing sections 24 and 32, as shown.

The side walls 43 of the hopper are provided in their bottoms with large rectangular openings 45, adapted to receive the inner opposed ends of the casing sections 24 and 32. Above the openings 45, the hopper side walls 43 are further notched or cut away at 46, for the reception of the upper mounting bolts 27, Figure 4. Shoulders 47 are formed by the tops of the openings 45 in the hopperside walls 43, and these shoulders may directly engage and rest upon the tops of the casing sections 24 and 32, as shown in Figure 7. The end walls 42 are spaced laterally of the side walls of casing sections 24 and 32, Figures 3 and 4, providing vertical passages 48 to convey the sand to the bottom of the hopper. The construction in effect forms hollow vertical legs in the hopper, at the opposite sides of the casing sections 24 and 32, extending from the top walls of the casing sections to the bottoms of their rectangular bores 25 and 33. These legs of the hopper, defining the vertical passages 48 areil 9lJ-shaped in transverse cross section, Figures 5 an In order to cover the bottom open ends of the vertical passages 48, I provide a horizontal transverse spacer bar 49 which extends between the inner opposed ends of the casing sections 24 and 32, level with their bottom walls, Figure 7. The spacer bar 49 ex tends beyond the opposite sides of the casing sections 24 and 32, and beneath the bottom ends of the hopper defining thel vertical passages 48, and the legs of the hopper preferably rest upon the bar 49, as shown. Outwardly of the side walls 42 of the hopper, the ends of the bar 49 are rigidly secured by welding or the like to sleeves 50, which slidably receive supporting bolts 51, extending rearwardly through openings 52, formed within the adapter plate 18. The bolts 51 are rigidly secured within the openings 52 by means of nuts 53, carried by the rear ends of the bolts 51, Figure 5.

The clamping plate 37 serves to cover the opening or notch 46 in the forward side wall 43 of the hopper, Figures 4 and 7, so that the sand cannot escape through this notch. The corresponding opening or notch 46 in the rear side wall 43, may be covered by an adjustable cover plate 54, having openings 55 receiving the bolts 27. Adjusting nuts 56 are mounted upon the bolts 27 adjacent the rear sides of plate 54, for holding this plate in closing engagement with the rear opening or notch 46, Figure 7. The top of the forward notch 46 may contact the top of the forward angle member 35, as shown in Figure 7.

I prefer to divide inspection doors or slides 57 at the bottom of the hopper, and mounted upon the end walls 42 thereof. The slides 57 are slidably mounted within wire holders or loops 58, rigidly secured t the end walls 42, and the slides are adapted to cover inspection openings 59, formed in the end Walls 42 at the bottom of the hopper. The openings 59 and slides 57 may be omitted entirely, if preferred.

It is thus seen that I have provided a sanding hop per which surrounds the top side and the two vertical sides of the clay bar 22, as the same passes through the casing sections 24 and 32. The hopper is positioned over the space or gap between the casing sections 24 and 32, and is adapted to supply sand to the three exposed spaces of the clay bar 22 as the same passes the space between the casing sections 24 and 32. The sand is fed by gravity to the bottom of the hopper, and the vertical passages 48 are lilled with sand, and the sand in the hopper directly engages the top and vertical side faces of the clay bar and will adhere to the same as it passes into the slightly enlarged forward casing section 32. The sand will be applied to the bar 22 evenly on the three exposed faces thereof, in a layer approximately 1/16 of an inch thick, and the sand will be smoothed over the three surfaces of the bar and embedded therein, as the clay bar passes through the casing section 32. Only the proper amount of sand will be applied to the three exposed surfaces of the clay bar and the bottom of the clay bar will receive no sand while passing over the spacer bar 49.

The construction of my sanding device is such that the hopper 41 may be bodily lifted from the remainder of the device at any time, without disturbing the bolts 27, casing sections 24 and 32, and associated elements. The bolts 27 pass through the cutouts 46, and when the hopper is lifted, the bolts pass freely through the bottoms of the openings 45.v

The amount of sand applied to the clay bar 22 may be further regulated and decreased by employing a narrower spacer bar 49, and arranging the casing sections 24 and 32 closer together, to narrow the gap between the same. The adjustable plate 37 and clamping angle members 35 may be moved rearwardly upon the bolts 27 for this purpose, and the sleeves 50 are slidable upon the bolts 51, thus permitting adjustment of the particular spacer bar 49. The narrower the space or gap between the casing sections 24 and 32, the less sand will be deposited upon the three faces of the bar 22.

After the sanded bar 22 emerges from the forward discharge end of the casing section 32, Figurel, the individual bricks are cut from the bar 22, by means not shown in the drawings, and the finished bricks, such as the brick shown in Figure l0 are formed, and sanded on their two ends and one side surface. The sanding of the bricks enhances their appearance, as is well known.

It is to be understood that the form of the invention, herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope of the subjoined claim.

Having thus described my invention, I claim:

A brick sanding device comprising an adapter plate to be secured to the discharge end of the extrusion die of a brick making machine and having an opening registering with the opening of the extrusion die, first and second rectangular tubular casing sections arranged in spaced aligned relation and adapted to receive a clay bar as the same is discharged from the extrusion die, scerw threaded rods secured to the adapter plate above and below said casing sections and extending longitudinally of the casing sections and over the space between the casing sections, clamping members connected with said rods and engaging the casing sections for rigidly securing them to the rods and said adapter plate, a sanding hopper arranged above the casing sections adjacent to their spaced apart ends and having side walls and end walls, the side walls having rst openings receiving the top and side walls of the casing sections and second openings above the first openings receiving the uppermost screw threaded rods, the end walls of the hopper extending adjacent to the side walls of the casing sections and spaced therefrom to form sand passages extending near the bottoms of the casing sections, cover plates mounted upon the uppermost screw threaded rods and covering said second openings of the hopper side walls, and a spacer bar arranged between the bottoms of the casing sections and covering the bottoms of said sand passages and supporting the hopper.
